Recent studies suggest that the anticancer activity of β-lapachone (β-Lap) could be improved by different types of bioactive phytochemicals. The aim of this study was to elucidate how the anticancer effect of β-Lap is regulated by polyphenols extracted from Korean L. (pKAL) in parental HCT116 and oxaliplatin-resistant (OxPt-R) HCT116 colorectal cancer cells. Here, we show that the anticancer effect of β-Lap is more enhanced by pKAL in HCT116-OxPt-R cells than in HCT116 cells via a CCK-8 assay, Western blot, and phase-contrast microscopy analysis of hematoxylin-stained cells. This phenomenon was associated with the suppression of OxPt-R-related upregulated proteins including p53 and β-catenin, the downregulation of cell survival proteins including TERT, CD44, and EGFR, and the upregulation of cleaved HSP90, γ-H2AX, and LC3B-I/II. A bioinformatics analysis of 21 proteins regulated by combined treatment of pKAL and β-Lap in HCT116-OxPt-R cells showed that the enhanced anticancer effect of β-Lap by pKAL was related to the inhibition of negative regulation of apoptotic process and the induction of DNA damage through TERT, CD44, and EGFR-mediated multiple signaling networks. Our results suggest that the combination of pKAL and β-Lap could be used as a new therapy with low toxicity to overcome the OxPt-R that occurred in various OxPt-containing cancer treatments.

Ferroptosis, a controlled cell death influenced by iron-dependent lipid peroxidation, presents potential therapeutic targets for cancer treatment due to its unique molecular pathways and potential drug resistance. Natural compounds, such as polyphenols, flavonoids, terpenoids and alkaloids, can influence ferroptosis via important signalling pathways, such as Nrf2/Keap1, p53, and GPX4. These are promising for combinational therapy due to their ability to cause ferroptotic death in cancer cells, exhibit tumour-specific selectivity and reduce systemic toxicity.

Background: Recent advancements in cancer therapeutics have catalyzed the development of noninvasive treatment modalities, including the utilization of fluorescent chemotherapeutic agents. These agents offer dual functionality, enabling targeted drug delivery, real-time tumor imaging, and personalized therapy monitoring. Such capabilities are instrumental in the progression toward more precise and effective cancer interventions.

Social wasps make up a significant part to the diversity of the Hymenoptera order, one of the most varied insect groups. Beyond their ecological importance, these insects use their venom for defense, protecting their colonies. The venom of social wasps are rich in biologically active substances, including biogenic amines, peptides, proteins, enzymes, allergens, and volatile compounds.

Platinum-group metal half-sandwich complexes are considered to be potential replacements of the clinically widely used platins which have several side effects and tend to cause resistance to develop. In our previous works, we used a range of 2-pyridyl-substituted N- and C-glycosyl heterocycles as N,N-chelating ligands to prepare ruthenium(II), osmium(II), iridium(III) and rhodium(III) polyhapto arene/arenyl half-sandwich complexes. Some of these complexes, particularly with the C-glucopyranosyl isoxazole derived ligand in its O-perbenzoylated form, exhibited greater anticancer efficiency than cisplatin and had minimal or negligible effects on non-transformed fibroblasts.

The persistent presence of the pharmaceutical pollutant nilutamide (NLT) in environmental and biological systems poses a serious threat to ecosystems and human health, necessitating efficient and sustainable detection strategies. In this study, we present a nanoengineered SrWO@MXene electrocatalyst as a high-performance platform for electrochemical sensing. The hybrid material seamlessly integrates the catalytic activity and electrochemical stability of SrWO with the exceptional conductivity and tunable surface chemistry of MXenes, resulting in a synergistic architecture optimized for rapid and selective NLT detection.
